Mammoth Cave Hotel Roof Replacement Project
The Mammoth Cave Hotel Roof Replacement Project will begin on Monday, December 6, 2021. The project will require the full closure of the main building of the Lodge at Mammoth Cave Hotel to the public for one year, but commercial visitor services, such as dining, retail and the hotel check in desk will continued to be offered near the visitor center. The project is funded through the Great American Outdoors Act (GAOA) and will help address the park’s backlogged maintenance needs and correct other exterior and interior deficiencies of the park’s main hotel building.
Air Quality Webcam
The park maintains an air quality monitoring station near the visitor center overlooking the Green River.
In cooperation with the US Geological Survey, the park maintains a water level monitoring station on the Green River inside the park boundary.
